HAIRPIN. 1

Application filed June 17,1922. Serial no. 569,009.;

To all whom it may concern:

Be it known that we, FRAN VINCENT, Kosafrlm and EDWARD STEPKAL, both oc1t An object of our invention is to provide a] hair pin which automatically locks itself in the hair.

A further object of our invention is to provide a hair pm which is simple moon-- struction and which is durable and efli'cient for the purpose intended.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claim.

7 Our invention is illustrated in the accoman in drawin s, formin 1 art of this a plication, in which p p Figure 1 is a front elevation of the. device, Figure 2 is a side elevation of the device,-

showing the hair pin in collapsed position,

and t Figure 3 is a side elevation of the device. Loss of hair pins is due to the fact that the pin is not clamped in position in the hair and therefore readily slides out. the present device, the wire 1 is curved in such a manner that it will automatically lock itself in place after once being disposed in the hain- In Figure 1 we have shown the wire 1 as being provided with a loop :portion 2, the sides 3 of the wire being again fashioned into a loop at, and into parallel end portions 5. The sides 3 are spaced from each other, as clearly shown in Figure 3,

so as to permit the hair to readily enter therebetween. The wire 1 is more or less flexible so as to permit the loop 2 to be compressed (see Figure 2) andthus move th ends 5 toward each other;

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. When inserting the hair ,pininto the hair, the 3 sides 3 are moved toward each other, as f shown in Figure 2.- Thepin is now inserted in thenhair, the pin being disposed in a vertical plane as it enters the hair to cause the ends 5-to receive the hair therebetween. By moving the pin into the hair, the recess 6, formed'by the spacedapart sides 3, receives the hair. Itis obvious that the sides 3 are swung slightly outwardly as the hair is forced into the recess 6, When the hair reaches the loop portions 2 and 4;, it tends to turn the hair pin into a position at right angles to a position from which it enters.

As soon as the pin is released, it will instantly-swing through an arc of 90 and liefiat against the head. The hair now eX- tends through theloops 2 and 4 and pre-' vents the pin from being removed until it is again turned through an arc of 90. From this operation, it will be apparent that the pin may be readily insertedin the hair of the wearer and be automatically locked in place when released, whereby the pin cannot drop out. The arrangement of the loops 2 and 4, and the spacing of the sides 9 u from each other, provides a simple means by whlch the spin is effectively locked in place in the hair. It is obvious that the pin is invisible when once inserted in the hai as is the ordinary hair pin. The device can be, ,manufactured cheaply and at slight expense,

Vi e claim: a I A halr pin comprising a wire bent back upon itself to provide hair engaging members, each member being provided with 1111- dulations or corrugations throughout a part of its length and being provided with a straight portion adjacent to its end, the un dulations of one member lying in one plane, the v planes of each member being spaced from each other, thereby permitting hair to be received between'said members, the hair lying in a plane parallel to the-planes of said members, the undulations of both members co-operating to form hair receiving loops, the hair when received in the loops extending'at right angles to the'planes of said members, one of the hair receiving loops being the/closed end of the hair pin.
